file 2音频/FluidSynth：[WinError 2]系统找不到文件

Question

在试图调用FileNotFoundError时，我得到了一个midi2audio错误。我正在使用Python3.6Anaconda-Windows 10，我的.py文件与.sf2和.mid文件位于同一个文件夹中。我的代码是：

from midiutil.MidiFile import MIDIFile

from midi2audio import FluidSynth
soundfont = 'C:\\Users\\matteo.stante\\Documents\\4_Python_Scripts\\experiments\\JR_sax.sf2'

filepath = 'C:\\Users\\matteo.stante\\Documents\\4_Python_Scripts\\experiments\\input.mid'

fs = FluidSynth(sound_font=soundfont, sample_rate=22050)

fs.midi_to_audio(filepath, 'output.wav')

我希望在我的文件夹中创建一个.wav文件。我得到的却是：

runfile('C:/Users/matteo.stante/Documents/4_Python_Scripts/experiments/AudioBello.py', wdir='C:/Users/matteo.stante/Documents/4_Python_Scripts/experiments')

FileNotFoundError: [WinError 2] Impossibile trovare il file specificato

Answer 1

soundfont = 'C:\\Users\\matteo.stante\\Documents\\4_Python_Scripts\\experiments\\JR_sax.sf2'

filepath = 'C:\\Users\\matteo.stante\\Documents\\4_Python_Scripts\\experiments\\input.mid'

• Windows：\ (为什么是2？因为\被格式化为\n \r .所以你需要2)
• Linux：/

如果文件位于同一个文件夹中，则

soundfont = 'R_sax.sf2'

filepath = 'input.mid'

编辑

我在我的电脑(windows 10)上试了一下，结果也出现了同样的错误。我没有找到任何关于OS的文档，但是很明显有一些linux命令。

在Linux操作系统上试一试

EDIT2

--我花了很少的精力，也在Linux上试了一下.

1)相同的错误-找不到文件

2)我发现您必须将文件夹放在路径-command：$PATH的某个地方

• 我把它放到/usr/local/bin/fluidsynth上

3)新错误:权限被拒绝(即使在根上也不能传递)

4)我发现我没有安装流体合成器

命令: apt安装fluidsynth

5)您的脚本工作正常(某种程度上，output.wav生成)

​

可能的解决方案

我相信，在linux上安装fluidsynth之后，您的windows解决方案将在Windows上安装fluidsynth之后得到解决。
